c簡單排序字串

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void strsrt(char *str[], int num)
{
char *temp;
int top, seek;
for (top = 0; top < num - 1; top++)
   {
for (seek = top + 1; seek < num; seek++)
       {
if (strcmp(str[top], str[seek]) > 0)
           {
//switch the value
               temp = str[seek];
               str[seek] = str[top];
               str[top] = temp;
           }
       }
   }
}
int main(void)
{
char *str[] = {
"test",
"hello",
"world",
"abc",
"hello two"
    };
    strsrt(str, 5);
　　
int i = 0;
while (i < 5)
        printf("%s\n", str[i++]);
return 0;
}

以上主要使用了strcmp()函數，實際上是排序了字串指標而不是字串，優點是保留了原始字串的順序

使用了最簡單的演算法，效率不是太高呵……
